no its not sea foam it looks like they hook up an iv stand to your car and run this chemical through your injectors but it works

ill probably have my car done just for good measure,and after watching it done i think it would be a benefit to do it every couple of years at least

there are a lot of good ideas to check here and just incase nobody mentioned it check all your intake hoses

i had a car that wouldnt idle at all and it was just holes in my intake hose,wrapped it in tape until the new one came and the car idled and ran just fine

my goofy ass spent about a month trying to figure it out and replacing stuff

one day decided to pull the accordian style hose off and stretched it to find all the holes,problem solved

O my car is fixed now -this is a old thread. But yeah I replaced several things trying to figure out the problem. My problem turned out to be the "F body speacialist" shop I took my car to. These dumb mf didnt gap the plugs and 3 were way too large a gap. Well apparently after running the car a few months with such a large gap it pretty much burnt up the end of the plug-and thats when the car started running like shit. Naturally, I assumed it wasnt the plugs or wires cause they were brand new. I got fucked by the local GM dealer when I took the car to them as well. Instead of putting my car on a diagnostic computer the did a injector flush and told me to come get the car " its running perfect now". I paid them $400.00(I knew I was getting fucked) and drove off. The car ran no better then when I dropped it off. I told them to put the car on the computer again and thats when they found the misfire in 3 cylinders. They kindly told me they would change my plugs and wires for $700.00 more Nice of them huh? All this happened because I had surgery and couldnt do my own work on the car. I finally found a honest mechanic and he put new plugs/wires on for $75.00.

Ask anyone on these forums if they let people drive their cars after a repair. They know better as well. In fact most everyone one these forums tries to do all their own work so shit like this doesnt happen. The only reason I took my car in for plugs was because of health reasons.

Well here a TSB.. For ya buddie... And I didn't mean no disrespect when i worte you that.. I was simily just stating a FACT bro..

**LETHALxLS1** · 02-01-2008, 11:23 AM

What fact are you stating? That its best to take a set of aftermarket plugs straight out of the pack and install them without checking the gap? Thats what you stated. I know that GM decided their plug gap of .060 to .040. My car is presently gapped to .035 and runs great. I also understand that certain plugs supposedly come Pre-gapped-but I would damn sure check each one myself before installing them.

I never said that you shouldn't check them.. U stated that.. All I said is that they come pre-gap already.. would it be wise to check them..? you bet, to make sure that they already gap to specs.

Before to verify the problem and after to make sure the problem went away.. But if you request it not to be driven then they should of just left it alone and wrote it down on the paper work(Not to be Driven after work).. The main reason shops do this is to protect them from getting sued in the court system..

I said that HUH? Right here is your post ^ I never said dont gapp the plugs wtf are you on?
